The correct answer is D) the chief steward's berthing quarters. The Coast Guard regulations require refrigerated spaces that can be locked from the outside and cannot be opened from the inside to have an audible alarm located in the chief steward's berthing quarters. This is to ensure that the chief steward, who is responsible for the safe operation of the refrigerated spaces, is immediately alerted if someone becomes trapped inside. The other options (the wheelhouse and the galley) are incorrect because the alarm is not required to be located in those areas.
